> The method {{getEnclosingMethod()}} in {{CtClassType}} (or {{CtClass}}) only works with non-constructor methods ({{CtMethod}}).
> However, the JVM's {{Enclosing Method Attribute}} is not restricted to non-constructor methods ({{CtMethod}}).
> Method-local inner classes can be declared within constructors.
> I suggest the addition of a {{getEnclosingBehavior()}} method as follows:
> {code:title=getEnclosingBehavior|borderStyle=solid}
> public CtBehavior getEnclosingBehavior() throws NotFoundException {
>     ClassFile cf = getClassFile2();
>     EnclosingMethodAttribute ema
>             = (EnclosingMethodAttribute)cf.getAttribute(
>                                             EnclosingMethodAttribute.tag);
>     if (ema != null) {
>         CtClass enc = classPool.get(ema.className());
>         String name = ema.methodName();
>         switch (name) {
>             case MethodInfo.nameInit:
>                 return enc.getConstructor(ema.methodDescriptor());
>             case MethodInfo.nameClinit:
>                 return enc.getClassInitializer();
>             default:
>                 return enc.getMethod(name, ema.methodDescriptor());
>         }
>     }
>     return null;        
> }
> {code}
